Nintendo Entertainment System Serial Numbers?
Are they actually worth something?!

Hey Retro. I need some help in identifying my two NES system's serial numbers. The only reason I ask is because I want to know if they're actually worth any money. If this is in the wrong section, feel free to move it.

Anyways, I have two NES systems, one owned by my mom and the other owned by my dad. My dad's NES' Serial Number is N4913238. This one came bundled with the Super Mario Bros + Duck Hunt multicart and the Grey Zapper, plus the texture of the system is plastic-like and very smooth. My mom's NES' Serial Number is N10025248, but here the texture is more rougher than my dad's NES (And it's a more darker grey color), plus she didn't have the Mario + Duck Hunt multicart, nor the Zapper. However she did recall owning the ROB, but she sold it to buy more NES games. This leads me to think that I have one of the original NYC Deluxe Test models in my possession, despite not having ROB in tow. Can anyone help me out in figuring out if that's the case? I would appreciate it!
